-   -   The input 64 bits of the EDMG-Header-B b=(b₁, b₂, . . . , b₆₄)         may be scrambled with PN sequence generated by a first LFSR,         e.g., LFSR 300 (FIG. 3) or any other LFSR, for example, starting         from the eighth bit to create a scrambled sequence bq=(bq₁, bq₂,         . . . , bq₆₄). The scrambler seed value may be initialized, for         example, by the first seven bits of the EDMG-Header-B, e.g.,         EDMG-Header-B 216 (FIG. 2). In other embodiments, any other         number of bits in the Header B field may be implemented for         initializing the scrambler seed.     -   The LDPC codeword, e.g., of length 672 bits or any other length,         may be created by concatenating a plurality of zeros, e.g., 440         zeros or any other number of zeros, to the scrambled header bits         bq=(bq₁, bq₂, . . . , bq₆₄) and then computing a plurality of         parity bits, e.g., 168 parity bits p=(p₁, p₂, . . . p₁₆₈) or any         other number of parity bits, for example, using an LDPC matrix         with R=¾ and/or L_(CW)=672 and/or any other parameters, e.g., in         accordance with Section 20.3.8.4 of IEEE 802.11-2016 or any         other Specification. The LDPC codeword may be defined, for         example, as follows: (bq₁, bq₂, . . . , bq₆₄, 0₁, 0₂, . . . ,         0₄₄₀, p₁, p₂, . . . , p₁₆₈). In other embodiments, a codeword of         any other length may be generated, for example, using any other         number of parity bits and/or zero bits and/or according to any         other encoding parameters.     -   The zero padded bits may be discarded and the output codeword         may be defined as c=(c₁, c₂), for example, wherein:         c ₁=(bq ₁ ,bq ₂ , . . . ,bq ₆₄ ,p ₁ ,p ₂ , . . . ,p ₁₆₀)         c ₂=(bq ₁ ,bq ₂ , . . . ,bq ₆₄ ,p ₁ ,p ₂ , . . . p ₁₅₂ ,p ₁₆₁ ,p         ₁₆₂ , . . . ,p ₁₆₈)     -   For a PPDU transmitted over a N_(CB)×2.16 GHz channel, wherein,         for example, the factor N_(CB) has a value of 1≤N_(CB)≤4 or any         other factor, the data block may be defined as a repetition of         codeword c by N_(CB) times, e.g., as follows:         cb=c for N _(CB)=1         cb=(c,c) for N _(CB)=2         cb=(c,c,c) for N _(CB)=3         cb=(c,c,c,c) for N _(CB)=4     -   The data block cb may be scrambled with a second PN sequence to         produce cq, for example, using a PN sequence generated by a         second LFSR, e.g., LFSR 400 (FIG. 4) or any other LFSR. The         scrambler seed value may be initialized, for example, to an         initial seed value equal to all ones (1₁, 1₂, . . . , 1₇), or         any other initial seed value. The scrambling may start, for         example, at the 225-th bit and/or may end at the (448×N_(CB))-th         bit, or any other range of bits.     -   For a PPDU transmitted using one or more, e.g., two, space-time         streams, the data block mapped to the first space-time stream         may be, for example, kept unchanged. For example, the data block         mapped to the second space-time stream may be circular shifted,         for example, by 4×N_(CB) bits, e.g., as follows:

  cq^(i_(STS  i_(user)) = 1) = cq cq^(i_(STS  i_(user)) = 2) = (cq_(4 × N_(CB) + 1), cq_(4 × N_(CB) + 2), …  , cq_(448 × N_(CB)), cq₁, cq₂, …  , cq_(4 × N_(CB)))

-   -   The input 64 bits of the EDMG-Header-B b=(b₁, b₂, . . . , b₆₄)         may be scrambled with a PN sequence generated by a first LFSR,         for example, in compliance with Section 20.3.9 of the IEEE         802.11-216 Specification, e.g., LFSR 300 (FIG. 3) or any other         LFSR, for example, starting from the eighth bit, to create a         scrambled sequence bq=(bq₁, bq₂, . . . , bq₆₄). The scrambler         seed value may be initialized, for example, by the first seven         bits of the EDMG-Header-B, e.g., as described above. In other         embodiments, any other number of bits in the EDMG Header B field         may be implemented for initializing the scrambler seed.     -   The LDPC codeword, e.g., of length 672 bits or any other length,         may be created by concatenating a plurality of zeros, e.g., 440         zeros or any other number of zeros, to the scrambled header bits         bq=(bq₁, bq₂, . . . , bq₆₄) and then computing a plurality of         parity bits, e.g., 168 parity bits p=(p₁, p₂, . . . , p₁₆₈) or         any other number of parity bits, for example, using an LDPC         matrix with R=¾ and/or L_(CW)=672 and/or any other parameters,         e.g., in accordance with Section 20.3.8.4 of IEEE 802.11-2016         and/or any other Specification. The LDPC codeword may be         defined, for example, as follows: (bq₁, bq₂, . . . , bq₆₄, 0₁,         0₂, . . . , 0₄₄₀, p₁, p₂, . . . , p₁₆₈). In other embodiments, a         codeword of any other length may be generated, for example,         using any other number of parity bits and/or zero bits and/or         according to any other encoding parameters.     -   The zero padded bits may be discarded and the output codeword is         defined as c=(c₁, c₂, c₃), for example, wherein:         c ₁=(bq ₁ ,bq ₂ , . . . ,bq ₆₄ ,p ₉ ,p ₁₀ , . . . ,p ₁₆₈)         c ₂=(bq ₁ ,bq ₂ , . . . ,bq ₆₄ ,p ₁ ,p ₂ , . . . ,p ₈₄ ,p ₉₃ ,p         ₉₄ , . . . ,p ₁₆₈)         c ₃=(bq ₁ ,bq ₂ , . . . ,bq ₆₄ ,p ₁ ,p ₂ , . . . ,p ₁₆₀)     -   In other embodiments, the output codeword may be defined based         on any other additional or alternative sequences.     -   For a PPDU transmitted over a N_(CB)×2.16 GHz channel, wherein,         for example, the factor N_(CB) has a value of 1≤N_(CB)≤4 or any         other factor, the data block is defined as a repetition of         codeword c bits, e.g., as follows:         cb=c for N _(CB)=1         cb=(c,c,c _(1:124)) for N _(CB)=2         cb=(c,c,c,c _(1:252)) for N _(CB)=3         cb=(c,c,c,c,c _(1:376)) for N _(CB)=4     -   The data block cb may be scrambled with a second PN sequence to         produce cq, for example, using a PN sequence generated by a         second LFSR, for example, in compliance with an IEEE 802.11ay         Specification, e.g., LFSR 400 (FIG. 4) or any other LFSR. The         scrambler seed value may be initialized, for example, to an         initial seed value equal to all ones (1₁, 1₂, . . . , 1₇), or         any other initial seed value.

For         example, the parameter N_(SD) may denote a number of data         subcarriers, for example, for an OFDM signal, e.g., at an EDMG         OFDM mode.     -   For a PPDU transmitted using one or more, e.g., two, space-time         streams, the data block mapped to the first space-time stream         may be, for example, kept unchanged. For example, the data block         mapped to the second space-time stream may be circular shifted,         for example, by 8×N_(CB) bits, e.g., as follows:

  cq^(i_(STS  i_(user)) = 1) = cq cq^(i_(STS  i_(user)) = 2) = (cq_(8 × N_(CB) + 1), cq_(8 × N_(CB) + 2), …  , cq_(2 × N_(SD)), cq₁, cq₂, …  , cq_(8 × N_(CB)))
